SPECIFICATION forming part of Letters Patent No. 481,111, dated August 16, 1892.

Application filed September 16, 1891. Serial No. 4:05.918. (No model.)

To all whom it may concern:

Be it known that I, Gonen HENRIE GLAD, a citizen of the United States, residing at Boston, in the county of Suffolk, and in the State of Massachusetts, have invented certain new and useful Improvements in Shutter Bowers and Fasteners; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view from the inside of a portion of a window and its shutters provided with my invention, one shutter being shown as closed and the other partly open; Fig. 2, a section, on an enlarged scale, taken on a horizontal plane through the locking device, showing both shutters closed and locked Fig. 3, a vertical section on the line as w of Fig. 2 Fig. 4, a detail perspective view of the locking device and its key separated from each other, and Fig. 5 a detail vertical section through the clamping device of the bower.

Letters of like name and kind refer to like parts in the several figures.

The object of my invention is to provide a simple, inexpensive, and efficient Window shutter, bower, and fastener or look; and to this end it consists in the device and the parts thereof constructed and combined substantially as and for the purpose hereinafter specifled.

In the drawings I show a portion of a window having hinged shutters or blinds A and A with my invention applied and arranged for practical use. To each shutter A, near the edge where it is hinged and on the side which is the inner one when closed, is fastened, as by screws, a plate having a horizontal proj ection a, to which is pivotally attached an arm or bar 13, whose other end is pivotally attached to a movable clamping device, to be presently described, that is in engagement with a long slotted or hollow bar 0, placed on and secured to the window-sill. Screws passing downward into the sill through vertical openings in the opposite ends of the bar serve to fasten the latter. The upper portion of the slot in the bar is narrower than the lower, being rendered so by an inwardly-projecting flange c on each side of it, in conjunction with which the clamping device before alluded to operates. Said device is constructed as follows: Extending upwardly between the flanges c and o and through an opening in the end of the arm B is a bolt D, having a square head (1, whose width is greater than that of the slot between the flanges, so as to engage with the under sides of the latter, and which is substantially the same as the slot immediately below them, so that by the contact of its sides with the sides of the bar B the bolt may be held from being turned. On a portion of the bolt that projects above the face of the arm B is a wing or thumb nut E, that is adapted to tightly bind or clamp said arm against the upper face of the bar O at any point along its length which it maybe caused to occupy by the move ment of the shutter from a closed to a fully open position.

To the upper end of the bolt D, at or somewhat above the point to which the thumbnut E rises on being turned to unclamp or loosen the arm 0 to allow the shutter to be moved, is fixed a stop, which may be, as shown, a screw F, tapped radially into the same, with its head left projecting beyond the face of the bolt to prevent the nut being turned entirely off the bolt either by accident or design. By the provision of this stop a possible source of frequent annoyance and inconvenience due to the removal of the nut is obviated. Instead of a screw a pin might be driven into the bolt, with a portion left projecting for the same purpose.

At the central portion of the bar 0 and within the same, so as to be housed and protected thereby, I locate a fastening or locking device by means of which the shutters when closed may be securely fastened or locked. This looking or fastening device or look consists of two spring-actuated latches G and G one for each shutterprecisely similar in shape but reverse to each other and pivoted both upon the same pivot g on a supporting-plate H. Said plate is secured to the inner side of the outer wall of the hollow bar 0 between two ribs 0 and c, which are provided thereon and made slightly undercut on their edges which are engaged by the edges of the plate, said plate-edges being accordingly correspondingly shaped. The plate H is slid up in place between the ribs from the bottom of the bar, and thus but one screw is needed to hold it in place, and that simply to prevent its dropping down. Preferably, too, the plate-engaging faces of the ribs converge toward each other upward, and the plate is accordingly shaped to facilitate the latters insertion between the ribs and its removal when necessary.

Near each end of the plate II is a round hole or opening 72, which registers with a like opening 0 in the outer wall of the bar C, and from said opening h rearward extends a hollow or tubular boss h, having an internal diameter the same as that of the opening. Through the openings 0 and it into the boss 7?. acylindrical projection I, secured to the shutter nearits outer edge, is adapted to pass, and when within said boss be engaged by the arm or extension 9 of the latch G, that passes through an opening in the side of said boss adjacent to the latch. The projection I is notched to form a lip '5 for engagement by the latch-arm g, whose rear face is made abrupt to most effectively do this, but whose front face is beveled, in orderth at when struck or pressed against by the end of the projection I it may be readily and automatically depressed to admit the same into the tubular boss to allow its lip i to be engaged by said arm when free to rise when the notch in the projection comes into alignment with it. As before indicated, the latch is springactuated and its spring keeps it normally in a raised or locking position. Said springis a coiled one and is placed in a cavity 9 formed in the face of the latch adjacent to the plate 11, with one end bearing against the upper wall of said cavity and its other against a horizontal lug or offset h on the lower edge of the plate H. Said lug has the same size and shape as the lower end of the cavity to entirely close the same, so that by it, the latch, and the plate H the spring is wholly housed and protected, being thus kept free from in jury or likelihood of displacement.

To enable the latches to be disengaged from the projections on the shutters, each latch on its edge which is adjacent to the edge of the other and at a point just above the pivot g has a notch or recess g, which when the latch is in its locking position is exactly opposite the similar notch g of the other latch. The space thus formed between the latches by these notches has a horizontal dimension less than its vertical dimension, so that by the insertion therein of a device or key similarly shaped or proportioned and then turning it said latches may both be simultaneously rocked to remove them from engagement with the projections Ion the shutters. Such a key I show consisting of a rod or bar K long enough to extend from the inside of the window horizontally outward through an opening in the sill and through an opening in the inner wall of the hollow bar 0 into the space formed by the notches 9 Its end where it engages the latches is flattened, and on the inner side of the window it is provided with a handle or thumb-piece 75, by which it may be turned. The opening in the window-frame through which the rod K passes at its inner end is covered by a metal plate L, held in place against the frame by suitable screws and having, of course, an opening for the passage of the rod, in which plate, on its side next the windowframe, is a cavity Z, containing a coiled spring M, adapted to be placed under compression by a radial lug k on the rod K by the turning of the latter to operate the latches. Said spring when allowed to exert itself upon the removal of the hand from the handle 70, restores said rod to its position for again operating the latches. The provision of this spring M relieves the springs of the latches G and G from the burden of turning the key K. A plate N, secured to the face of the plate, extends over the spring M and operates to confine or hold it in the cavity Z. \Vhen the latches G are released from the projections I, the latter are instantly ejected from thetubular bosses out of the way of the latches, to avoid re-engagement by them, by means of a coiled spring 0, placed in each of said bosses between the rear abrupt side of the latcharm and the inner wall of the hollow bar 0. Said spring is compressed by said projection on its entering the boss, and has across its end a plate or disk 0 for the projection to strike or bear against.

Although both latches are simultaneously operated to release the shutters it will be apparent that but one shutter, if desired, may be closed and locked without the other, each latch in this respect being capable of operation independently of the other.

If it should not be convenient to attach the bar 0 in place by screws passing vertically into the sill, a set of horizontal holes cis provided to enable screws to be used in horizontal positions.

My device is simple and cheap to manufacture, yet entirely eflicient for the object or purpose designed.

By having the clamping-bar 0 made in one continuous piece for both shutters, instead of a separate bar for each shutter, and placing the shutter-lock in and securing it to the bar, the device as a whole is not only rendered most compact and convenient for vending; but the work of putting it into place is very simple and easy in comparison with what is necessary in cases where separated bowing and locking devices are employed. No cutting of the sill or frame has to be resorted to to accommodate the locking mechanism, except a hole for the key or latch operating device, as the whole of said mechanism except the latter is within the bar 0, being incased and protected thereby, so as to be safe from injury and tampering.

Having thus described my invention, what I claim is- 1. In combination with the clamping-bar of a shutter-bower, a shutter-lockin g device attached thereto, consisting of a plate with two spring-actuated latches pivoted thereon, sub stantially as and for the purpose specified.

2. In combination with the clamping-bar of a shutter-bower, a shutter-locking device attached thereto in a space or cavity, so as to be inclosed, substantially as and for the purpose shown.

3. In combination with the hollow clampingbar of a shutter-bower having provision for engagement of two clamping devices,a shutter-lock secured in said bar between the latter, substantiallyas and for the purpose described.

4:. In combination with the clamping-bar of a shutter-bower having a cavity with converging sides, a plate carrying shutter-locking means in said cavity and conforming in shape thereto, substantially as and for the purpose set forth.

5. In combination, two oppositely-rocking pivoted latches rocking onacommon horizontal pivot and having adjoining edges Vertically to one side of said pivot, and a key adapted to rock said latches by engagement with said edges, substantially as and for the purpose specified.

6. In combination, two oppositely-rocking pivoted latches rocking on a common horizontal pivot and havingadjoining edges above said pivot, between which is a space narrower than long, formed by notching each latch edge, and a key conforming in shape to said said boss, substantially as and for the purpose shown and described.

9. In combination with the clamping-bar of a shutter-bower, the arm or bar for connection with a shutter, and the device to clamp the latter to the former, consisting of a bolt and a nut thereon, said bolt passing entirely through the nut and having a screw with a portion projecting beyond its periphery-to limit the movement of said nut along it by engagement with the upper side of the nut, substantially as and for the purpose shown. In testimony that I claim the foregoing I have hereunto set my hand this 4th day of September, 1891.
